Does a divorce occur with the husband's statement: "You remain divorced, for your lifetime, a first divorce," if he claims he did not intend divorce?

It is not clear whether the husband made the divorce contingent upon something or executed it immediately. If he did not make it contingent, then his divorce is effective whether he intended it or not, because his utterance is explicit. If this was the first or second divorce, then he has the right to take back his wife before her waiting period (iddah) expires. It is advisable to present the matter to trustworthy scholars in the questioner's country.
